A professor wanted to study whether there was an association between a person's age
and their likelihood to use social media. He surveyed members of Gen Z, Millennials, and Gen X.
Below you will find the data that was collected:
YES, use social media
NO, do not use social media

a. Perform a Chi-Square Test for Association to see if there is evidence to show there is an
association between age and likelihood to use social media?
